Modify driver for multiple process access?

[drew-os]

I'm trying to create eNB and UE instances on a ZCU111 to do some testing. Eventually I want to expand this to multiple UE instances. In trying to run the run_lte.sh script (with some modifications) it was able to successfully open the RF device to create the eNB (srsenb), but when it tried to do the same for the UE there's this error:

zynq_timestamping/sw/lib/src/phy/rf/xrfdc/rf_xlnx_rfdc_imp.c:220: Error opening device '/dev/srs_rx_dma'
Unable to open RF device 'RFdc'

I noticed it also reconfigures the LMX clocks, so it's going through the full device initialization again. Does anyone know how to modify either the software or the driver to allow multiple processes to access the RF device?
